CARRIER.

SPECIFICATION forming part of Letters Patent No. 788,838, dated May 2.1905.

' Application filed May 9 1904. Serial No. 207,030.

To a whom it may concern:

Be it known that LEDwAan C. LnoNARDsoN, a citizen of the United States,residing at Wa terloo, in the county of Jefferson and State ofWisconsin, have invented certain new and useful Improvements inCarriers, of which the following is a specification, reference being hadto the accompanying drawings, forming a part thereof.

i This invention relates to elevated carriers designed to automaticallydump their loads at predetermined points in the line of their travel.Its main object is to provide a simple and effective latch and automaticlatch tripping mechanism for this purpose.

It consists in certain novel features of construction and in thepeculiar arrangement of parts hereinafter particularly described, andspecified in the claims.

I In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is aside elevation of a piece of track and of an elevatedcarrier to which my improvements are applied, parts being broken awayand shown in section. Fig. 2 is a plan View of one end of the dump-boxand a section on the line 2 2, Fig. l, of associated parts of the latchand hanger; and Figs. 3 and I are detail views of the latch andassociated parts.

The carrier comprises a trolley adapted to run on an elevated wire ortrack a, a hanger, and a dump-box pivotally connected with the hangerand suspended by it from the trolley, all of the usual or any suitableconstruction. As shown in the drawings, the trolley consists of twogrooved wheels I) b and a sheet-metal frame a, bent to form a housingfor the wheels and to support the ends of the wheel-axles. The hangerconsists of a horizontal bar (Z, attached to adepending part of thewheel housing or frame below and parallel with the trolley-wheels andthe track on which they run, and a bail c, which may be fixed orremovably hung upon the bar cl, its depending arms being provided attheir lower ends with boxes ff. A dump-box c, constructed of wood or anysuitable material, is provided at the ends, preferably below its centerof gravity, with trunnions it it, which are fitted in the boxes ff ofthe hanger.

The dump-box is held in upright or carrying position with its open topuppermost, as shown in Fig. 1, by a latch or look consisting of twomembersa longitudinally-movable locking-bar 2' and a keeper The bar viis arranged in a substantially vertical position parallel with one ofthe hanger-arms and between it and the adjacent end of the dump-box. Itis pivoted at its upper end to a horizontallydisposed lever It,fulcrumed on the bar Li, and is held at its lower end in proper workingrelation to the other member of the latch by guides Z and m. The keeperj may be made. as shown, in the form of a vertically-grooved boss castwith the sdjacent trunnion-plate, as shown in Fig. 4E, and the guide mmay be made, as shown, in the form of a verticallygrooved lug cast withthe adjacent trunnionboxf'. The guide Z, which is located above and inline with the guide on, consists of a loop through which the locking-barpasses, formed on a collar which is pinned or otherwise fastened on theadjacent hanger-arm.

A cam n, pivoted to the hanger-bar (Z, bears against one arm of thelever k, supporting the locking-bar i either in looking position, asshown in Fig. 1, or in an elevated position out of engagement with thekeeper j. The working face of the cam is preferably formed on one side,as shown, with a flange or lip which projects over the lever is andserves, with the opposing face of the bar cl, to retain it in place. Thecam is reversible or of such shape, as shown, that when it is turned ineither direction from its central or normal position in which it isshown in Fig. lit will lift the locking-bar out of engagement with thekeeper j. It is provided with an upwardly-projecting arm 0, which isolfset laterally at its upper end to insure its engagement with a tripattached to and depending from the track It at the point where it isdesired to dump the carrier.

The latch and tripping mechanism operate as follows: The parts of thelatch and tripping mechanism being in the positions in when the arm 0strikes the trip 9 it is turned backward, tilting the lever 713 andwithdrawing the locking-bar c' from the keeper 1', as indicated bydotted lines. The box g being thus released, automatically swings intoan inverted position and dumps its contents. Upon the return of thecarrier to the starting-point, this being usually accomplishedautomatically by the inclination of the track a, the dump-box is turnedback into an upright position and locked in that position by loweringthe bar c' into engagement with the keeper the cam 72 being returned toits central or normal position to release the dumpbox when the carrieris again run to the dumping-point. The cam 22 being reversible, as abovestated, the carrier may be run in either direction with the same result,the latch being automatically disengaged and the dump-box released whenthe arm 0 strikes the trip 2, so that, if desired, trips may be providedat distant points and the carrier run from an intermediate point inopposite directions and automatically dumped at either of those distantpoints, or in case it is reversed in position upon the track theoperation of the latch and tripping mechanism will not be aflected.

The device as herein shown and described is of simple construction andis reliable in operation.

Various changes in minor details of construction and arrangement ofparts may be made without departing from the principle and intendedscope of the invention.

I claim- 1. In an elevated carrier the combination of a trolley adaptedto run on an overhead track, a hanger suspended from said trolley, adumpbox pivotally connected with said hanger, and a latch andlatch-tripping mechanism comprising a keeper on the box, alongitudinallymovable locking-bar adapted by engagement with the keeperto hold said box in upright position, a lever adapted to withdraw saidbar from engagement with said keeper andacam arranged to act upon saidlever and having an arm adapted in its normal position to be engaged bya trip in its line of travel, substantially as described.

2. The combination with an elevated track, of a carrier comprising atrolley adapted to run on said track, a hanger, a dump-box pivotallyconnected with the hanger and suspended thereby from the trolley, akeeper on said box, a locking-bar mounted on said hanger and movablelongitudinally into and out of engagement with said keeper when said boxis in upright position, a lever connected with said bar, a cam foroperating said lever and having an arm projecting normally toward thetrack, and a trip on the track in the path of said arm in its normalposition, substantially as described.

3. In an elevated carrier the combination with a trolley adapted to runon an elevated track, a hanger having depending arms connected at theirupper ends with the trolley, and a dump-box pivoted at its ends to thelower ends of said arms, of a latch and latchtripping mechanismcomprising a keeper on said box,a longitudinally-movable lockingbarhaving a guide on one of said arms and adapted by engagement with saidkeeper to hold the dump-box in upright position, a reversible cammounted on said carrier and having an arm projecting normally intoposition to be engaged and turned back in either direction by a trip inits path, and a lever connected with said locking-bar and arranged to betilted by the rocking of said cam in either direction from its centralor normal position, substantially as described.
